Air source heat pumps for homes and businesses in Osea Island
In England, an air source heat pump on a house can often go in under permitted development rights. The conditions include an outdoor unit of no more than 1.5 m³ and compliance with MCS 020(a), and the unit cannot be used solely for cooling or sit within the curtilage of a listed building. We look at the planning position for your home during the survey. We are often asked to deal with deciding on the outdoor unit position and questions about the Boiler Upgrade Scheme, across air-to-air heat pumps, hot water cylinders and air-to-water heat pumps.
For a home around Osea Island that is off mains gas and heated by oil or LPG, an extra £1,500 is available through the Boiler Upgrade Scheme until March 2027, on top of the £7,500.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

What else we do in Osea Island
How it works
Each visit runs to the same pattern: check the plan with you, protect the area, carry out the job, check the system and talk you through it. On site, the work takes anything from a couple of days for air-to-air to the best part of a week for air-to-water with radiator changes. A note on how to find the property and where to park makes a visit to Osea Island easier.
- First, a chat about the property and your goals for the heating.
- The survey checks heat loss, emitters, hot water and the outdoor unit position.
- We explain which type of heat pump suits the home and whether a grant could apply.
- We install the heat pump and connect it up.
- We commission it, complete the MCS certificate and show you how to use it.
Preparing for the visit
- Clear access to the fuse board
- Give us access to the outside wall, roof or yard where the outdoor unit sits
- Plan for pets to be kept clear during the visit

Advice
What the work involves, system by system
Air-to-water heat pumps
Air-to-water systems work at lower temperatures than boilers, which is why radiator sizing is part of the survey.
Heat loss surveys
We look at walls, windows, floors, roofs and ventilation along with the room sizes.
What a heat pump looks like in Osea Island
Osea Island is within about 2 miles of the coast. Salt air is hard on outdoor units, so a heat pump near the sea needs a sensible position and regular checks, and some models offer corrosion protection for coastal sites. The last census (2021) found about 83% of households in detached or semi-detached houses. Houses usually have space for an outdoor unit and a hot water cylinder.
Grant applications go through the MCS certified installer, so that part is handled for you. Every heat pump design starts with a room-by-room heat loss calculation.

Osea Island questions
Will you come out to Osea Island?
Yes. Osea Island is within the area we cover across London and the South East. We’re based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Does sea air affect air conditioning in Osea Island?
It can, as Osea Island is within about 2 miles of the sea, where salt in the air is hard on coils and fixings. The outdoor unit position, its fixings and regular servicing all help near the sea.
Do you offer emergency call-outs?
Yes. For anything urgent, such as a system failing in a server room or water leaking from a unit, ring our 24/7 line and we’ll agree what happens next.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and explain why.
Do you look at the job first?
Yes, every time. We diagnose before we treat: the survey tells us what the job needs and how to do it and the fixed price is built on it.
How quickly will you reply?
You will hear from us the same working day. If it’s an emergency, ring the 24/7 line instead.
Is a heat pump permitted development?
Many installations on houses in England fall under permitted development, subject to the rules. Listed buildings are excluded, and listed building consent is separate, so we check for your property.
